Description
PCB 21 is a polychlorinated biphenyl reference standard at 100 µg/ml in isooctane for environmental analysis and gas chromatography. This ROTI®Star solution is supplied in a 1 ml glass unit and is intended for calibration, system suitability checks and quantitative GC determinations of the PCB 21 congener. Solvent-related properties include a density of 0,69 g/cm³, a flash point of -12 °C and a boiling point of 99,2 °C, with UN number 1262 applying to the isooctane matrix. Such data assist laboratories in assessing flammability controls, transfer steps and chromatographic conditions. The standard from manufacturer Carl ROTH fits workflows that prefer a lower stock concentration for multi-level calibration or reduced carry-over risk. Packaged as 1 ml glass, it is practical for occasional use and controlled inventory of single-congener PCB materials. Typical application areas cover environmental monitoring, chromatography method development and gas chromatographic separation of polychlorinated biphenyls where a defined 100 µg/ml PCB 21 solution in isooctane is specified.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 21, 100 µg/ml in isooctane, 1 ml, glass
What is this article?
PCB 21, 100 µg/ml in isooctane, 1 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
